JAMES S. STEPHENS, OF BOND, ARKANSAS.

PLOW-COLTER.

To all whom 225 may concern:

Be it known that I, JAMES S. STEPHENS, a citizen of the United States,residing at Bono, in the county of Craighead and State of Arkansas, haveinvented certain new and useful Improvements in Plow- Colters, of whichthe following is a specification, reference being had to theaccompanying drawm s.

This invention relates to plow colters and more particularly to meansfor adjusting the colter with relation to the plow point, the inventionhaving for its primary object to provide an adjusting means for thispurpose of simple, durable and eflicient construction whereby the coltermay be very easily and quickly adjusted and rigidly held in position.

Another and more specific object of the invention is to provide incombination with a plow beam, a standard, said beam being provided withan opening therein to receive the colter, plates mounted upon the upperand lower sides of the beam and provided with openings coinciding withthe opening in the beam, and means for moving the uppermost plates toangularly dispose the colter with relation to the longitudinal axis ofthe plow beam.

With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a side elevation of a plowprovided with my improved colter adjusting device; Fig. 2 is an enlargedlongitudinal section of the rear end of the plow beam and a portion ofthe standard.

Referring in detail to the drawing 5 designates a plow beam and 6 thestandard thereof which is secured to the rear end of the beam in anyordinary or approved manner and is provided at its lower end with ashovel or plow point indicated at 7. The beam 5 is provided adjacent toits rear end with a vertical opening 8, the rear wall of which isinclined downwardly and inwardly Specification of Letters Patent.

from the upper surface of the beam as designated at 9. Through thisopening in the plow beam the upper end of the colter 10 is adapted to bedisposed. Upon the top of the beam 5 the longitudinally movable plate 11is arranged, said plate being provided in its forward end with anelongated rectangular opening 12 to receive the colter 10. A rod 13 isintegrally formed with or secured upon the rear end of this movableplate and is disposed at a slight upward inclination from the uppersurface of the plow beam, the rear end of said rod being looselydisposed through an opening in the plow standard. The extreme rear endof the rod extending rearwardly of the standard is provided with screwthreads to receive a suitable adjusting nut 1 L whereby said rod may bemoved through the standard to slide the plate 11 upon the upper surfaceof the plow beam. The adjusting plate 11 is also provided adjacent itsrear end with a second longitudinally extending elongated opening 15 fora purpose which will be apparent from the following description.

A plate 16 is arranged upon the adjusting plate 11 and is provided withan opening 17 to coincide with the opening 12 in said adj usting plateand to receive the upper end of the colter 10. The rear end of thisupper plate 16 is also provided with an opening 18 to register with theopening 15 in the rear end of the adjusting plate. The forward end ofthe plate 16 is provided with a rectangular longitudinally extendingopening 19, and the upper surface of the plate around the edges of saidopening is grooved as indicated at 20. This grooved surface is adaptedto receive the ribs 22 of a washer plate 21.

Upon the under side of the plow beam 5 a longitudinally disposed plate23 is arranged, and upon the rear end of said plate a connecting rod 24is formed which extends through an opening in the plow standard andconnects said plate thereto, a suitable securing nut 25 being threadedupon the end of said rod. Beneath this plate 23 at its inner end theplate 26 is arranged, the forward end of said plate being provided witha longitudinal slot or opening 27. The rear end of the plate 26 isnotched or recessed as indicated at 28 to receive the forward edge ofthe colter 10, said bottom plate 28 being provided with an opening J)through which the colter is disposed.

Front and rear bolts 30 and 81 respectively are disposed throughvertical openings in the plow beam and through the ends of the upper andlower plates 16 and 23. The forward bolt 30 extends through the opening27 in the plate 26, said plate being longitudinally movable upon thebolt whereby the inner edge of the recess 28 in the rear end of saidplate may be maintained in close frictional contact with the edge of thecolter 10. The upper end of this bolt 30 extends through the slot 19 inthe forward end of the upper plate 16, the washer 21 being provided witha central opening to receive said bolt. Upon the up per end of the bolt30 a nut 32 is threaded to rigidly clamp the washer plate 21 upon thegrooved edge of the opening 19. The rear bolt 31 extends through therear end of the lower plate and through the registering openings 15 and18 in the upper. plates 11 and 16 respectively. This bolt also has asuitable nut 33 threaded upon its upper end whereby said plat-es may berigidly held in position against relative move ment.

From the above the construction and manner of operation of my improvedcolter adjusting device will be fully understood. \Vhen it is desired tochange the position of the lower end of the colter with relation to theplow point or shovel, the nut 1 1 on the rear end. of the rod 13 isturned to move the sliding plate 11 forwardly or rearwardly upon theupper surface of the beam 5, it being understood of course, that thenuts 32 and 33 on the upper ends of the bolts 30 and 31 have first beenloosened. In this sliding movement of the plate 11, the uppermost plate16 will also be moved upon the upper ends of said bolts, the slots inthe ends of said plates being of suliicientlength to permitthe rear edgeof the colter 10 to engage with the inclined wall 5) of the opening inthe beam so that said colter may be disposed at a forward inclination.As the opposite ends of the slots 12 and 17 in the plates 11 and 16respectively engage upon opposite edges of the colter, it will bereadily seen that when the nuts 32 and 33 have been tightened, saidcolter is rigidly held in its position in the beam. In the manner abovedescribed, the colt-er may be very easily and quickly adjusted to thedesired position.

The device is comparatively simple in construction, may be inexpensivelymanufactured and will efficiently perform the functions for which thesame is devised.

While I have shown and described the preferred construction andarrangement of the various elements, it will be understood that theinvention is susceptible of considerable modification without departingfrom the essential feature or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is 1. Thecombination with a plow beam and standard, said beam having an openingtherein provided with a rear inclined wall, of superposed plateslongitudinally movable upon the upper surface of the beam and havingcoinciding openings,a longitudinally disposed plate fixed upon the lowersurface of said beam and also having an opening coinciding with theopening in the beam, a colter adapted to be disposed through the openingin the beam and the openings in said plates, the longitudinal edges ofsaid colter bearing upon the end walls of the openings in the plates, aplate longitudinally slidable upon said lower plate having a notch inone end to receive the colter, said latter plate being provided with anelongated opening in its other end, the uppermost plate of saidsuperposed plates also having an elongated opening in one end, a boltdisposed through the beam, the opening in said upper plate and theopening in the lower slidable plate, said upper superposed plates beingprovided with additional openings, and a bolt disposed through the beamand the latter openings of the superposed plates to secure saidsuperposed plates upon the beam and to permit of the relativelongitudinal movement of the lower superposed plate.

2. The combination with a plow beam and standard, said beam beingprovided with an opening having a rear inclined wall, of superposedplates mounted upon the upper surface of the beam and having. openingsto coincide with the openings in the beam, a colter adapted to bedisposed through said openings in the beam and plates, a plate arrangedupon the lower surface of the beam and rigidly fixed there to, a plateslidably mounted upon said latter plate and provided with a recess inone end to receive the edge of the colter, means for longitudinallymoving the lower one of the superposed plates upon the upper surface ofthe beam, the upper plate being provided with an offset end extendingbeyond the end of the lower plate and closely engaging upon the beam,said offset end of the plate being provided with an opening, saidslidable plate which is arranged beneath the plate on the bottom surfaceof the beam being also provided with an opening, In testimony whereof Ihereunto aifix my a bolt disposed through said openings and signature inthe presence of two Witnesses. the bottom plate and through the beam,and
